After The Leavenworth Case
The Poisoned Chocolates Case by Anthony Berkeley
If The Leavenworth Case's forensic precision and layered logic seduced you, The Poisoned Chocolates Case takes that intellectual thrill further: six brilliant minds construct entirely different airtight solutions to one poisoned murder, each dismantling the last. It's Golden Age mystery as cerebral art—refined drawing rooms, poison timelines worthy of a chemist, and the same triumph of wit over violence that made you fall for Green's pioneering puzzle. Your deduction skills have never faced a gauntlet this elegant.
